For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] A photovoltaic tracking system for an agricultural photovoltaic complementary project includes a main beam 3 mounted above a plurality of columns 2 and at least one slewing drive 4;

[0040] The rotary driver 4 is provided with a transmission gear 41, a limit block 42 and a shaft connection member 43;

[0041] The main beam 3 extends in the horizontal direction; the shaft connecting member 43 is sleeved on the outer circumference of the main beam 3, and the outer circumference of the shaft connecting member 43 is sleeved with a shaft sleeve; the outer circumference of the transmission gear 41 is continuously arranged with a plurality of gear teeth 411 arranged along the circumference, and the plurality of gear teeth 411 are meshed with the shaft sleeve;

[0042] The side surfaces of the limit block 42 are used to abut against the two outer gear teeth 411 to limit the stroke of the transmission gear 41; the limit block 42 is symmetrically distributed on the vertical plane where the center point of the rotary driver 4 is located; the plurality of gear teeth 411 are asymmetrically distributed on the vertical plane where the center point of the rotary driver 4 is located, and the maximum arc angle corresponding to the openable gap between the outer gear tooth 411 and the limit block 42 is greater than 90°.

[0043] like Figure 1-3 As shown, the photovoltaic tracking system for the agricultural-photovoltaic complementary project of the utility model is set up on the top of multiple columns 2, and the main beam 3 can be driven to rotate through the rotary drive 4, and the multiple solar cell modules 1 suspended on the main beam 2 can be driven to rotate accordingly, so that the panel surface of the solar cell panel can obtain vertically irradiated sunlight; because the arc angle corresponding to the gap between the outer gear 411 and the limit block 42 is greater than 90°, when harvesting equipment needs to pass under the solar cell module 1, the rotary drive 4 can be controlled to drive the transmission gear 41 to drive the main beam 3 and the multiple solar cell modules 1 to rotate together until the irradiation surface of the solar cell module 1 is parallel to the ground, so that the solar cell module can avoid blocking the harvesting equipment, which provides convenience for the harvesting of crops and improves the harvesting efficiency.

[0044] The maximum arc angle corresponding to the openable gap between the other gear tooth 411 located on the other outer side and the limit block 42 is greater than 60°.

[0045] Furthermore, it also includes at least two fisheye bearing seats 5;

[0046] The two fisheye bearing seats 5 are inserted on the top of the two columns 2; the rotary drive 4 is located between the two fisheye bearing seats 5;

[0047] A spherical joint bearing 51 is installed in the fisheye bearing seat 5;

[0048] The spherical joint bearing 51 is sleeved on the outer peripheral surface of the main beam 3 .

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, when the column 2 is installed upright on a slope, if there is an installation error during piling, the verticality of the column 2 will deviate. The main beam 3 with multiple solar cell modules 1 suspended thereon is mounted on the top of the two columns 2 through a spherical joint bearing 51. Under the action of gravity, the spherical joint bearing 51 will adaptively adjust the horizontality of the main beam 3, which can reduce the installation difficulty of the photovoltaic tracking system for the agricultural-photovoltaic complementary project and ensure the operational effectiveness of the photovoltaic tracking system for the agricultural-photovoltaic complementary project.

[0062] The controller 7 includes a tracking device for tracking the sunlight irradiation angle.

[0063] like Figure 1 and Figure 2 As shown, when harvesting equipment needs to pass under the solar cell assembly 1, a signal can be sent through the remote controller, and the wireless signal receiver 8 receives the signal sent by the remote controller and transmits it to the controller 7. The controller 7 controls the rotary drive 4 to start, and drives the transmission gear 41 to drive the main beam 3 and multiple solar cell assemblies 1 to rotate together, while timely adjusting the positions of the multiple solar cell assemblies 1 so that the harvesting equipment can pass smoothly.

[0064] When the angle of sunlight changes and reaches a set threshold, the controller 7 controls the slewing driver 4 to start, and drives the transmission gear 41 to drive the main beam 3 and multiple solar cell assemblies 1 to rotate together, so that the panel surface of the solar cell panel can obtain vertical sunlight, thereby improving the power generation efficiency.
